Just wanted to point out something I noticed. Rendering with NV Encoder is much faster but the video quality is actually noticeably worse. I shot some videos in 60fps and slowed them down 50% so to get the best slow motion I would render in 30 fps right? Then there's the option of using Optical Flow, Frame Blend or Disable Resample. I found that Disable Resample actually produced the best looking slow motion in combination with rendering with the Main Concept encoder. Anyone got any other tips when it comes to the highest quality render. Oh I'm talking about rendering in 4K as well. I shoot in 5.3k but render in 4K.

For best render quality, check Voukoder for Vegas (https://www.voukoder.org/).

For a 50% slomo of 60fps videos, import those videos at project framerate (right click media in project media tab and choose "add at project framerate", project framerate should stay 30fps), no need for resampling in that case (optical flow, frame blend).

You are correct. The characteristics of Machine Encoders including your NVENC, as compared to traditional Software Encoders like MainConcept and Voukoder x264 are:

1. Hardware Encoders are much faster to acquire and encode. This is the main reason they exist.
2. Hardware encoded video is inherently worse quality than software encoded video. Often much worse, as measured by objective and subjective benchmarks.
3. Hardware encoded files are larger than their software counterparts, usually much larger.
4. Hardware encoded files are harder to decode and edit on your NLE, such as Vegas.
5. Software encoders come in three flavors -- Mathematically Lossless, Visually Lossless, and Lossy Compressed. Hardware encoders come in but two flavors -- Semi Ugly and Ugly.
6. Gamers, Hobbyists, and uncritical millenials like Hardware encoders because they are fast. Video Producers and Postproduction Editors like Software encoders because they are accurate, sharp, more efficient for editing, and are always of better quality at the same file size.

There are very few exceptions to these characteristics. You can pretty much take them at face value.

Welcome to the discussions. 🙂

Great wording."Software encoders come in three flavors -- Mathematically Lossless, Visually Lossless, and Lossy Compressed. Hardware encoders come in but two flavors -- Semi Ugly and Ugly."

I confess; the beer made me say it.

As you can see from my picture, I also like beer.

After passing on current Intel cpus for a new system, been looking at the Intel Core Ultra igpu specs and was surprised to see onboard fp64 support. Don't know if that might be used in qsv encoding but if so, it could have a major effect on render quality.
